Extreme density and temperature allow the transition for the ordinary matter to the deconfined phase, in which quarks and gluons are free from their parent hadrons and they can interact with each other. Such conditions can be reached by ultrarelativistic heavy ion collisions. Different phases of evolution of the matter are predicted according to theoretical … Continue reading Evolution of collisions and QGP

Beyond the force that holds us back in bed in the morning, there are other four fundamental forces, in Nature. At the present state of our knowledge, Nature is presented as the result of the composition of the four fundamental interactions (electromagnetic, weak, strong and gravitational) with a set of elementary particles which can be classified according … Continue reading Particles and forces
